It’s not exactly new but there will be an extra star in the sky that will be visible to the naked eye in the coming months in Northern California. T Coronae Borealis is a binary star system comprised of a cool red giant and a hot white dwarf star 3,000 light years away. The smaller white dwarf has been stealing matter from the red giant and appears to be getting ready to emit a burst of energy which will make it visible for at least a few days. It is known as a recurring nova where matter, mostly hydrogen, is collected by the white dwarf until enough mass is reached, creating a fusion reaction. That will then emits a burst of energy, which includes visible light. This process has been going on for a long time and occurs about every 80 years in this system.
